The object of t is invention is the production of a rail-stayin which the two rail-gripping aws are provided with means whereby these jaws are guided in their movement toward each other when the same are drawn together to cause them to gri the rail between them. This guiding may e either to minimize the tilting strain on the jaws when drawn toward each other. or to prevent lat eral displacement of the jaws relative to each other or for other purposes.

ed to effect both of these results; but n iy invention contemplates, broadly, the provision of means for accomplishing either of these results. and a modified form of device, also shown, vis adaptecl' to resist the backward tilting only. i

EXtOIltlyi vices ofthis character it happens at times 4 that ahasty or careless workman wilUapply the device so that the jaws are not exactly opposite each other, and consequently the bolt extends diagcnally across the base of the rail. Therefore ifsthe parts are so con structedthat either of the jaws can be swung lengthwise of the rail until the bolt is brougl'it'squarely across the base of the rail any strain which tends to bring this about will result in loosening: the gripof the jaws upon the rail-base; but..w ith myimproveuent 'in wliicli'the lower extensions of the jaws eoengage each other so as to provide longitud nal guides, such faulty application of the device becomes l-lllDtSSlblt.

In the form of device shown in Figs. 6. 7,

and 8 the interengaging extensions are given the form oi overlapping parts M and N.

The niuwally-engaging ends of these extensions are preferably given a form similar to that of the-familiar scarf-jointzg When this "device is applied to the base of a rail and the i adapted to engage the opposite edges of the .nut f upon the bolt F: is-tightened, the part therail} v It will-be observed that each jaw and its N will be forced up into engagement withihe base of the rail and the part M willbe forced up against the lower side of the scanfed port1on of the part N and also will engage throughout a portion of itslength the base of extension under-the rail Constitutes roughly a bell-crank lever, which is fulcrum'ed upon the edge of the base-flanged the rail. Consequently there is a'tendency to rock upon the rail-base when the bolt is tightened,'and' I lwithsome constructions of this t the objection has been sometimes'made thate ofanti creeper this-rocking tendenoy su, jects the bolt to avertical-'strain-and interferes to some extent. with' theefficiency of the device. By overlapping the extended por tions of the jaws I am enabled to give each.

=In Fig. 9 is shown a cross-sectional View of A a further modified term of my invention.-

In this form of rail-stay the extensions O and'P are given an inverted-U form. W hen gather, the part P is fcrced'upward into closer engagement with the'base of therail and the part 0 is forced up against the part P. In this form of the device, as wellasin thatshown Figs. 1' to 5,. these extensions serve to maintain the jaws in alinement with each other and with the bolt F.

In Fig. 10 is shown a ficrm of rail-stay in which but one of the jaws is provided with a depending part J, adapted to engage the tie. In this devicethe tight ning-of the nut f upon the bolt F tends to throw the extensions K and L up into engagement with the rail-base, so that the tilting of the. j aws back ward away from the rail is prevented, as in the other forms of the device. I claim 1 4 1. In a rail-stay the combination of a pair of jaws adapted to" grip the opposite edges of the base-flange of a rail, each of said jaws being provided with a horizontal portiqn which extends beneath the rail-base and which overlaps such horizontal extension of theopposite jaw, and means for holding said jaws in gripping engagement with the railbaso.
